What even is a casual relationship?

Help this brother out! Matched with this girl on Hinge, at that time, she mentioned on her profile that she is looking for short term, I went out with her, interesting part, we never had a chat online , I directly asked her that was my first question, just saw an activity in her profile that I have in common and invited her to that. We spent like about 2 hours and went our ways. I understood that she is planning on moving to CA, searching for a job. Been in Chicago for like 2.5 years.

Lol we have a lot in common, same hometown, we family background etc… wasn’t knowing any of this until I met her. lol right after our date, I checked her profile, she added an explanation to her profile, saying, she is not looking for a relationship, but maybe something casual. I haven’t asked what she is looking for when I met in person, right now I’m confused what is casual, did she mean just hooking up with anyone?

I didn’t get this feeling that she is into hookups when I met her, she was warm and nice to talk to, she was genuinely curious to know me etc… felt like a proper date.
